I've been eagerly anticipating Dr. Jason Lisle's paper in the Answers Research Journal concerning a possible solution to the distant starlight problem, and it has finally arrived! I've read it over once, and a lot of it is over my head, but I think I get the gist of it. If you haven't read it yet, here's the link: Anisotropic Synchrony Convention

Upon re-reading the technical paper by Dr. Hartnett, I think I have your answer.
The principle source of time dilation, according to Hartnett is not gravitational, but rather due to the velocity of the expansion of space. Therefore the depth of the gravitaitonal well is not the primary concern, rather, the rate of the expansion of space is of utmost importance. Any gravitational time dilation would simply add to the effect of cosmological expansion.

Actually it wouldn't if everything started with a diameter of 100,000 light years across (the size of our galazy). Time would be the same for the entire space. Once the universe started expanding then the gravity well would begin decreasing and time would speed up for the outer edged of the universe but time would remain the same for everything in the gravity well. It would still take 50,000 earth years for us to see the light at the edges of the universe.
From what I remember from reading his book the velocity of space may speed time up for the objects going fast but it doesn't for the objects going slow or standing still. There's still the issue of the light that starts from objects 50,000 light years away reaching the earth in less than 50,000 years. The whole universe would have had to be bunched so tightly in an area of about a light year in radius for us to be able to see the edges of the universe in a year. Our nearest star is more than a light year distant from us. This is one advantage Humphrey's model, with areas of timelessness, has over Hartnet's model in my mind.
